Design And Implementation Of KM2406 Antenna Radiation Near-Field Measurement Data Processing System

KM2406 is a data processing software system developed for various antenna radiation near-field measurement platform which goal is to provide data analytic support for engineers for the commonly used plane radiation near-field measurement tasks. This thesis presents the design and implementation of this software from the software engineering's view.The thesis works on the requirement analysis, software design, programming and tests from the perspective of microwave antenna measurement and data processing. This software's major functions include measurement tasks management, data processing and data visualization. The function of measurement tasks management manages the task setup, option setup, data installation and processing in units of tasks in practice of radiation measurement in order to raise the tasks'accuracy and efficiency. The function of data processing realizes the measured data samples processing such as the radiation field's amplitude and phase relationship analysis, directional diagram evaluation based on the theory of advanced digital signal transformation and processing techniques. In addition this software provides one and two dimensional radiation field's distribution graphics.KM2406 is programmed with C++ and its programming model while it can be integrated with general relational database by call standard interface components to construct a complete data storage platform. Its data visualization uses the mainstream OpenGL graphical library with wide suitability. Through comparisons under various conditions there comes the conclusion that KM2406 near-field radiation measurement data processing system is of the same precision class as the imported products in comparison which can be applied to industrial level detections.
